Pictures at an Exhibition presents images of one notable show every weekday.

Today’s show: “6 ½ Weeks. Dorota Walentynowicz and Nanna Krogh Lauritsen: Outside in – Inside out” was on view at the Museum Folkwang in Essen, Germany, from January 25 to March 11. The two-person exhibition, which presented a total of 20 works, looked at the ways in which both artists, who fabricate their own pinhole cameras, “use their work to explore the opposing poles of exterior and interior worlds in photography,” according to a press release.
